Hi All, 1) Free DNS services : For volunteers who are interested in binding your dialup, cable or adsl connections (IP) with a easy to remember domain (sub-domain) name please check with DyNS website. If you have a server running services such as ftp, telnet, ssh or http, a domain name (eg. mydomain.dyns.cx) can be created above and mapped to your IP (203.125.x.x) so that you'll be able to access your machine via the domain name eg. ftp mydomain.dyns.cx. Here are a few more such free services : www.ods.org

PS: many free DNS service providers offer update clients for automatic updates (IP-DNS name mapping) when your internet connection is made. 2) Firewall softwares: For free basic software for windows machine, please check here : http://www.zonelabs.com/ .
